GEORGE B. NORGRAVE, OF PEABODY, MASSACHUSETTS.

ROOF-JOINT.

To all whom it may concern:

Be it known that I, GEORGE B. NOR- GRAVE, a citizen of the United States, residing in Peabody, in the county of Essex and State of Massachusetts, have invented an Improvement in Roof-Joints, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to a roof joint for soil pipes, and has for its object to provide a simple and eflicient device, which is capable of conforming to any angle or pitch of the roof without altering the device and with which a water-tight joint is obtained with the soil pipe and with flashings of standard or regular size, which joint is unaffected by settling of the roof. To this end, the device is provided with a short upright end portion which is substantially semi-circular in form, and with a long opposite end portion, which is inclined downwardly away from said upright end portion and is substantially elliptical in shape so as to form an elongated opening at its top and bottom, whereby the device can be tilted or inclined in the direction of the long axis-of the top opening, on a pipe whose diameter is substantially equal to the width or shorter axis of the elongated opening, so that the device may be made of iron or other rigid material and in one piece and yet be adjusted to roofs of different pitches on a pipe of the diameter substantially equal to the shorter axis of the top opening, which is made of a length greater than the diameter of the pipe and such that its opposite ends will make contact with the opposite sides of the pipe when the device is applied to a roof of maximum pitch.

The body portion of the device referred to is provided at its upper end with a hub which is constructed so as to retain the oakum and lead usually employed for effecting a water tight joint between the soil pipe and the roof joint, and yet allow of the adjustment of the roof joint to roofs of different pitch.

These and other features of this invention will be pointed out in the claims at the end of this specification.

Figure 1 is a plan view of a roof joint embodying this invention, as applied .to a roof having a maximum pitch and shown in Fig. 3. Fig. 2, a vertical section of the roof joint shown in Fig. 1 in operative position on a Specification of Letters Patent.

roof approximately flat. Fig. 3, a like section showing the joint applied to a roof having a maximum pitch. Fig. 4:, a side elevation of the roof joint before being applied to the pipe and resting on a horizontal base.

Fig. 5, a plan view of the roof joint shown in Fig. 4, as applied to a pipe on a substantially flat roof, and Fig. 6, a section on the line 6- 6, Fig. 5, with the pipe in elevation.

Referring tothe drawing, (t represents a roof, and b, a soil pipe extended up through it and over which is fitted a device or roof joint 0, which, in accordance with this invention is provided with a body portion having a short upright end portion (1, which is substantially semi-circular in form and having a downwardly inclined opposite end portion c, which is substantially elliptical in form and which forms with the shorter upright end portion an elongated opening at the upper part or top of the device and a larger opening at the bottom of said device.

The body portion is preferably provided on its inner side near its top with an annular flange or bead 10, which serves as a support for the packing material 7L and also serves as a bearing to facilitate adjustment of the joint to the pipe and roof", materially reducing the amount of packing required.

The annular bead or flange 10 forms the walls of the elongated top opening and is composed of two end curves 20, 21, connected by substantially straight intermedi ate side portions 22, 23 (see Fig. 5).

The upper part of the body portion may be enlarged to form a hub 13 for the reception of the lead or other packing'material 7t, now commonly used and by means of which a water-tight oint about the soil or other pipe I) is obtained. The lower end of the body portion is provided with an outwardly extended flange "i, which may have suitable I holes or openings 7', preferably countersunk,

and which are designed to be filled with solder or other metal, which is poured into the said holes or openings to form rivets 7:, which are united with the solder an employed on the copper flashing, which latter may be of the standard or usual construction and comprises the parts n, 0, the part 0 extending up into the body portion of the roof joint and having an outwardly extended flange 5 upon which is soldered the part a, which latter is united to the flange i of the roof joint by the rivets it.

It will thus be seen that the flashing is firmly secured to the roof joint and is held up by the latter and prevented from dropping down with the roof a in case the latter settles, thereby avoiding the danger of leaks oc curring between the roof joint and flashing from the settling of the roof.

In Fig. 1, the roof joint is represented as applied to a roof of maximum inclination, shown in Fig. 3, with the result, that the elongated opening at the top of the body portion is not shown as clearly as in Fig. 5, which is a lanview of the roof joint as applied to a lat or substantially flat roof, and

y reference to Fig. 5, the invention may be more clearly seen than in Fig. 1.

Referring to Fig. 5, it will be seen that the flange or bead 10 forms the wall of the top opening in the body portion of the device,

and that this wall is composed of curved end portions 20, 21, which are struck from different centers but of equal radius, the curve 20 being struck from the center 26, and the curve 21 from the center 25. The ends of the curves 20, 21 are joined by substantially straight intermediate portions 22, 23 forming the sides of the elongated top opening.

It will be also observed that the radius of the curves 20, 21 is the same or substantially the same as that of the external circumference of the pipe I), with the result that the curve 20 makes contact with the pipe in all positions of the roof joint or device and that the curve 21 makes contact with the opposite side of the ipe when the roof joint is applied to a roof 0 maximum pitch as shown in Fig. 3. The elongated to opening permits a roof joint of rigid material, such as iron, to be tilted or turned when on the pi e I) so as to conform to roofs of different inc nations' In Fig. 6 the roof oint is shown in the position it would assume on a flat roof, and by reference to this figure, it will be seen that the curve 20 of the flange or bead 10 is in contact with the pipe I), while the curve 21 is out of contact therewith.

In Fig.2, the device is shown as applied to a roof having what may be considered a slight pitch and in this case, it will be seen that in adjusting the device to the pitch of roof the long side of the device is lowered fromthe position shown in Fig. 6, and that the device turns on the curved end portion 20 of the flange or bead 10 as a pivot.

In Fig. 2, it will be observed that the curved end portion 21 is still separated from the pipe by a considerable space. In Fig. 3, the device is shown as applied to a roof of maximum pitch and in this case it will be seen that the curved portion 21 of the flange or bead 10 makes contact with the pipe on the side opposite to that which is engaged by the curved portion 20 of the flange or bead, but at a materially lower point on the pipe. The'hub portion of the device is also provided With an elongated opening, whose long longer side 6 of the body portion is curved and struck from the center 18, while the inner circumference of the portion of the hub which extends from the short upright side d, is struck from a different center, namely, 28. The curve struck' from the center 18 is of the same radius as the curve struck from the center 28, and consequently the hub 18 is provided with an elongated o ening in the form of an' ellipse, which al ows for the proper space for the reception of the calk ing or packing inthe different positions into which the roof joint or device may be adjusted, as clearly represented in Figs. 2, 3 and 6 and which also permits of the adjustment of the roof joint to roofs of different pitch, while yet serving to retain the packing material with which a water-tight joint is obtained between the roof and the soil pipe.

By reference to Fig. 3, it will be seen that when the device is applied to a roof of maximum pitch and the end walls of the top opening in the body portion engage the op posite sides of the pipe I), that the contacting points of the end walls of the opening are separated a materially greater distance than the diameter of the pipe, and that said opening is materially longer than the diameter of the pi e, although the width of the opening is of t e same or substantially the same diameter as the pipe. The bottom opening formed by the downwardly inclined side 6 is also materially longer than the top opening, and by means of this construction, the roof joint may be made in one piece of iron or other rigid material and yet be capable of being fitted over a pipe of a diameter substantially equal to the width of the to opening and be adjusted thereon to con orm to the pitch of the roof, which may vary from a substantially flat roof to one having a pitch of forty-five degrees.

From the above description, it will be seen that the roof joint is simple in construction and can be applied in the least possible time, as it is only necessary to drop or slip the same over the soil pi e, thereby materially reducing the cost 0 the joint and the time and labor of applying the same.
